If that were true, then it would not be linear.

I believe that the degenerate search will still be proportional to the square
root of the nodes of the minimax search.

It should be easy to test, if someone has an interest.  Just change your move
ordering function to pick a random move instead of the pv node.

Try some searches at various depths for various positions.

Then we can match mental extrapolations to measurements.
